GROOVE-CUTTING ATTACHMENT Foa SEWING-MACHINES.

SPFCIIEICATION forming part of Letters Patent No. 543,431, dated July 23, 1895.

Application filed September 11,1890. Serial No. 364,614. (No model.) d

To all whom it may concern;

Be it known that I, AGUsrUs G. TAYLOR, a citizen of the United States, residing at Peterborough, in the county of Hillsborough and State ofNew Hampshire, have invented certain new and useful Improvements in Groove- Cutting Attachments for Sewing-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a sewingmachine known as the fair-stitch machine, employed for sewing ha-rness, belts, boots, shoes, and the like.

The invention consists of a rotary vibrating cutter mounted in front of the needle, so that ,as the material is fed toward the needle a groove or channel is cut-therein.

vzo

Referring to the accompanying drawings, Figure 1 1s a perspective view of afair-stitch machlne having an attachment according to my invention for sinking the stitches below the surface. Fig. 2 is a side view of my at tachment for sinking the stitches below the surface.

` B being the needle-bar, and O the presserfoot.

D is the horn, E the driving-pulley, and F a wheel mounted upon a shaft G, to which motion is'imparted from any suitable source, the wheel F communicating motion to the pulley E by abelt H, all in the ordinary manner.

and to therear of the horn is pivoted a bearing J, and a bearing K is also fulcrumed 'to the body of the machine. In these bearings is mounted a shaft L, upon which is secured a pulley M driven by a belt P from a pulley To the loop-former is secured a bearing 1 N on the shaft G.' The outer end of the shaft L is turned down to a smaller diameter and,

the tendency is to tighten it upon the shaft.

The object of having the two bearings .I K

pivoted is to allow for the movement made by the loop-former. As the front bearing I is secured thereto it has, of course, a corresponding reciprocating movement imparted to it.'

L L are collars to prevent the shaft L from working out of the bearing.

The rotary cutter Q is of such a diameter that it projects the desired distance through and above the needle-plate, according to thedepth of groove itis desired to cut in the leather, .so as to embed the stitches.

`In operation the leather to be stitchedis fed in the ordinary manner, but as it comes into contactwith the rotary cutter Q just before it comes to the needle (the cutter being on a line with the same) it is cut or grooved out-so` that the stitches are formed in the groove and not upon the surface of the leather, as with some fairlstitch machines now in use.

W'hat-I claim as my invention is In combination withl a fair stitch sewing machinea rotating vibrating shaft L, mounted in pivoted bearings J, K, and bearing I, secured to the loop former, a rotary cutter Q, mounted on the end of said shaft on a line with but in advance ofthe needle and means for imparting a rotary motion to said shaft substantially as set forth. I

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this lst day of September, A. D. 1890.

Witnesses: C. A. JAQUITH, S. R. CUTLER.
